It is the Bluetooth version (but the silkscreen on PCB mentions LD2410 without the B). For Android, use app from the Play store (HLKRadarTool). UART is connected to the USB. Has 2 LEDs: red power LED and green LED when person is detected. IMPORTANT: Does not work with USB-C/USB-C cable or charger. It has USB-C port, but does not support USB PD, so the charger (or port on laptop) won't provide any voltage and it will not power on. You must use USB-A / USB-C cable.

Well constructed radar module to detect presence. Better than IR ones that could be affected by thermal variations. I haven't tested yet if my module has Bluetooth capability.

Just put this into my PC ; the proprietary android app is necessary, it won't pair with phone / PC - however the module is amazing, the tiny board is the actual radar with the host doing bluetooth & USB interface. The USB generates a stream of data incoming, which I intend to examine with interest! Have found a manual for the actual radar module here https://hlktech.net/index.php?id=988 - no info on commands or outputs though. For the price, amazing!
